How is the most important knowledge transmitted in primitive society and civilization?

In primitive society, important information was passed down from generation to generation, that is, from father to son. In the days of ancient civilizations, this form of information transfer also existed, but there were already schools where teachers passed information to their students. In addition, there were books that contained important information about the life of past generations. Although we can say that a significant part of the information that concerns everyday life, both in primitiveness and in our time, is transmitted through parents.
